23 | /* Length of echobuf field in each KBOARD. */ |

25 | /* Each KBOARD represents one logical input stream from which Emacs |
26 | gets input. If we are using ordinary terminals, it has one KBOARD | |
27 | object for each terminal device. | |
931e7866 RS |
28 | Usually each X display screen has its own KBOARD, |
29 | but when two of them are on the same X server, | |
30 | we assume they share a keyboard and give them one KBOARD in common. | |
31 | ||
32 | Some Lisp variables are per-kboard; they are stored in the KBOARD structure | |
33 | and accessed indirectly via a Lisp_Misc_Kboard_Objfwd object. | |
34 | ||
35 | So that definition of keyboard macros, and reading of prefix arguments, | |
36 | can happen in parallel on various KBOARDs at once, | |
37 | the state information for those activities is stored in the KBOARD. | |
38 | ||
39 | Emacs has two states for reading input: | |
40 | ||
41 | ** Any kboard. Emacs can accept input from any KBOARD, | |
42 | and as soon as any of them provides a complete command, Emacs can run it. | |
43 | ||
44 | ** Single kboard. Then Emacs is running a command for one KBOARD | |
45 | and can only read input from that KBOARD. | |
46 | ||
47 | All input, from all KBOARDs, goes together in a single event queue | |
48 | at interrupt level. read_char sees the events sequentially, | |
49 | but deals with them in accord with the current input state. | |
50 | ||
51 | In the any-kboard state, read_key_sequence processes input from any KBOARD | |
52 | immediately. When a new event comes in from a particular KBOARD, | |
53 | read_key_sequence switches to that KBOARD. As a result, | |
54 | as soon as a complete key arrives from some KBOARD or other, | |
55 | Emacs starts executing that key's binding. It switches to the | |
56 | single-kboard state for the execution of that command, | |
57 | so that that command can get input only from its own KBOARD. | |
58 | ||
59 | While in the single-kboard state, read_char can consider input only | |
60 | from the current KBOARD. If events come from other KBOARDs, they | |
61 | are put aside for later in the KBOARDs' kbd_queue lists. | |
62 | The flag kbd_queue_has_data in a KBOARD is 1 if this has happened. | |
df631feb | 63 | When Emacs goes back to the any-kboard state, it looks at all the KBOARDs |
931e7866 RS |
64 | to find those; and it tries processing their input right away. */ |
